Evaluation on Arrear Electricity Charges Based on Multi-attribute Group Decision Making Considering User Payment and Abnormal Electricity Consumption

The pattern of electricity consumption first and charge then will bring difficulties in recovering electricity charges to the power supply enterprises, which may cause economic losses and operational risk to the power supply enterprises. To evaluate the risk of abnormal electricity consumption and overdue charges, the power supply enterprise can pay attention to the high-risk users, which can re-duce the possibility of pecuniary loss. This paper proposes a method for assessing the arrearage risk of users considering payment and abnormal electricity consumption based on multi-attribute group decision making. Firstly, the evaluation index system including user payment and abnormal electricity consumption is determined. Secondly, the entropy weight method is used to determine the index weight. Then the analytic hierarchy process and the relative distance are used to determine expert weight. Combined with attribute weights and expert weights, the fuzzy comprehensive evaluation model is used for evaluation. Finally, the evaluation results are ordered according to the worst indicators, and the user's risk rating is provided.
